In the context of global joint response to climate change, carbon neutralization has become one of the main measures for governments, enterprises, and even individuals around the world to deal with global warming. This article explores the current research status and frontier trends in the field of carbon neutralization, which can not only provide theoretical reference for the follow-up research of carbon neutralization but also provide useful ideas for the policy-making of carbon neutralization. The study is built on the China National Knowledge Infrastructure (CNKI) Core Journals Database, the Chinese Social Sciences Citation Index database, and the Chinese Science Citation Database as the literature retrieval database platform. Using CiteSpace optical measurement software, 370 pieces of literature in the field of carbon neutrality research in China were systematically analyzed to track the situation and impact of research by various research institutions and prominent authors in China in this field and to analyze the research hotspots in this field, which is of great significance for the follow-up research of carbon neutrality. The research results show that 1) the number of publications in China’s carbon-neutral field has increased significantly with the change of years and has strong development potential. 2) Journals with many articles are more concentrated and are generally published in three journals: Natural Gas Industry, Proceedings of the CSEE, and Chinese Science Bulletin. 3) In terms of the major research institutions, the Institute of National Conditions of Tsinghua University, the School of Public Administration of Tsinghua University, the School of Grammar of Beijing University of Technology, and the Economic Development Research Center of the State Forestry and Grassland Administration have published more articles and muscular scientific research strength in the field of carbon neutrality. 4) In terms of the principal authors, four typical research teams have been set up: low-carbon economy, low-carbon cycle, carbon trading, sewage carbon neutrality, environmental science, and resource utilization, and the authors of each research team cooperate closely. 5) In the future, the research hotspots in China’s carbon-neutral field are still the themes of carbon emission reduction, green and low carbon, new energy, etc., and the research hotspots have begun to shift to the concept of development, from the very beginning of environmental protection and carbon emission reduction to the current new energy development. Carbon neutrality is currently a hot research field in China, and in the future, special attention should be paid to the full use of machine learning and extensive data mining to solve complex social, economic, and ecological problems. It is suggested that China should introduce the concepts of “common but differentiated responsibilities” and “consumer responsibility” in the international climate change negotiations in the formulation of carbon neutralization policies, so as to fully protect the right to the development of China’s underdeveloped regions and avoid the injustice caused by the blind formulation of carbon neutralization policies.Systematic Review Registration: [https://review.frontiersin.org/review/896524/16/1295417/#tab/History]

We used the carbon carrying capacity as an indicator of environmental productivity, clarified the emission reduction thresholds and measures for achieving a carbon neutral tourism destination, and proposed a simple, objective, and universal method for estimating the carbon budget of forest tourism scenic spots with function of both carbon sinks and carbon emissions. According to the Intergovernmental Panel on Climate Change Guidelines for Greenhouse Gas Inventories and the Climate Friendly Parks tool, a carbon emissions list with a clear border and relatively complete content was established to characterize the negative impact of tourism activities on the environment. Forest resource inventory data and the CO2Fix method could be used to accurately calculate the carbon sinks of forest tourism scenic spots. In 2019, the total CO₂ emissions in Shenyang National Forest Park were 1841.445 t. The amount of CO₂ sequestered by the forest was 1336.787 t, accounting for 72.59% of the total CO₂ emissions. Thus, tourism had a net CO₂ deficit of 504.658 t. Electricity consumption, garbage disposal, raw coal consumption, infrastructure construction, and land-use changes of forestland were the top five sources of CO₂ emissions. The augmentation of the carbon pool could be improved by 65.358% of the total budget through forest management. The reduction aims of 133.41%–150.32% could be easily reached through emissions-cutting measures. Based on these results, we suggest several measures for low-carbon sustainable tourism.
